A run level is the operating state of the operating system. Run levels can be: "halt", "single user mode", "multi-user mode", "reboot", "graphical user interface mode/display manger" and others. Each run level starts or kills a set of processes and is denoted by a number typically from 0 to 6. Different operating systems may define different run levels.
